10G-EPON ONU Burst-Mode Employing Dynamic Save Control Circuit
2015/5/18
Symmetric 10G-EPON ONU burst-mode transceiver employing dynamic power save control circuit was, for the first time, developed. Reduction of power consumption up to 37.7% was successfully achieved with...
The so-called symmetric H Hs state has been reported to have submillisecond response times, which results from the symmetric profile of the liquid crystal director; however, no direct evidence has b...
